Successful treatment of Candida krusei fungemia with amphotericin B and caspofungin.

We report a leukemic patient with C. krusei fungemia who failed to respond to liposomal amphotericin B therapy alone. The addition of caspofungin eradicated infection and was well tolerated. Our report is the first to describe successful treatment of a patient with invasive C. krusei infection using this combination of antifungals. Combination therapy could be a useful treatment option for invasive candidosis, particularly when caused by more resistant species such as C. krusei.
